This session demonstrates practical techniques that drop a web page's size from almost 3MB to 143K, and load time from 4 seconds to less than a second—while looking the same! Review tools that validate and describe performance best practices. Explore how to defer resource requests, load resources asynchronously and prefetch critical resources. Many other performance improvements will be discussed, which can reduce response time while also boosting the scalability and reliability of your site. Learn the techniques that can have the largest impact on web performance with the least amount of work. Use webpagetest.org, Fiddler and Lighthouse to measure your web site and find the best opportunities for improvement!
